ACR1222L FF 82加载身份验证密钥失败，并显示63 00操作失败 [英] ACR1222L FF 82 Load Authentication Keys fails with 63 00 Operation Failed

问题描述

我正在将ACR1222L NFC智能卡读卡器与Mifare Plus卡配合使用（到目前为止，安全级别为0；制造商默认键为A和B）。我尝试了各种命令将身份验证密钥加载到阅读器中：

I'm using ACR1222L NFC smartcard reader with Mifare Plus cards (Security Level 0 as of now; manufacturer default keys A and B). I tried a variety of commands to load authentication key into the reader:

FF 82 00 00 06 FF FF FF FF FF FF
FF 82 00 01 06 FF FF FF FF FF FF
FF 82 20 00 06 FF FF FF FF FF FF
FF 82 00 00 06 A0 A1 A2 A3 A4 A5
FF 82 00 00 06 D3 F7 D3 F7 D3 F7
... and others ...

所有这些都返回错误状态：

All of them are returning the error status:

63 00 (Operation Failed)

怎么了？我已经搜寻了很多提示，但是其他许多问题是关于身份验证失败或使用上述命令之一成功加载身份验证密钥后之后失败，并且这些问题通常基于不同的设备（

What could be wrong? I have searched long and wide for a hint, but many other questions are about failed authentication or failed read after successfully loading authentication key with one of the above commands, and they are often based on a different device (ACR122U).

我注意到读卡器不存在时读者甚至不响应命令。读卡器上应该有卡可以加载身份验证密钥吗？

I noticed that the reader does not even respond to the command when a card is not present. Should a card be present on the reader for it to load authentication key?

推荐答案

要能够使用诸如 加载身份验证密钥，（块）身份验证，读取，写入，更新等，该卡必须处于安全级别1 或更高级别。

To be able to use the commands such as "Load Authentication Key", "Authentication (of a block)", Read, Write, Update, etc, the card has to be in Security Level 1 or higher.

通过将一些相关密钥加载到卡中，可以使用某些命令将卡从安全级别0移动到安全级别1。请联系 ACS 获取这些命令，因为它们尚未公开记录。

There are certain commands to move the card from Security Level 0 to Security Level 1 by loading several relevant keys into the card. Please contact ACS to obtain these commands as they are not publicly documented.
